Question

我写了一个没有for循环的代码，请为我提供解决方案，通过for循环更新它，创建或替换程序PR_UPDATETBEMP（COMM IN NUMBER）AS

begin
  UPDATE XX_TBEMP
  SET COMM=SAL*.05
  WHERE SAL BETWEEN 80000 AND 99999;
end PR_UPDATETBEMP;

Answer 1

create or replace PACKAGE XX_UPDATETBEMP AS
PROCEDURE XX_UPDATECOMM;
end XX_UPDATETBEMP;

create or replace PACKAGEBODY XX_UPDATETBEMP  AS 
PROCEDURE XX_UPDATECOMM IS
CURSOR C_TBEMP IS SELECT * FROM XX_TBEMP;
R_TBEMP C_TBEMP%ROWTYPE;
BEGIN

FOR SAL IN C_TBEMP
LOOP
UPDATE XX_TBEMP
      SET COMM        =  sal * 0.2 where SAL BETWEEN 30000 AND 49999;
      UPDATE XX_TBEMP
      SET COMM        = sal * 0.15 where SAL BETWEEN 50000 AND 79999;
      UPDATE XX_TBEMP
      SET COMM        = sal * 0.1  where SAL BETWEEN 80000 and 99999;
END LOOP;
END XX_UPDATECOMM;
END XX_UPDATETBEMP;
